The Metrology 101 article from the Jul-Sep 2013 issue, “Testing Linearity on the Agilent E441xA Power Sensors,” has been updated online. The upper and lower readings are incorrect in the printed version. An Excel spreadsheet […]
by Michael Schwartz Today’s new high dynamic range power sensors are not built the same as the older generations of sensors. Older generations of power sensors only had a correction table for their frequency response. […]
by Charles Sperrazza Verification of the Standing Wave Ratio (SWR) of the 50 MHz 1 mW output power reference is a key step in performing a calibration of a RF power meter. Higher than desired […]
by Agilent Technologies Connectors, adapters, and calibration standards in the millimeter-wave frequency range (26 GHz to 70 GHz) are VERY expensive. Although all connectors eventually wear, with knowledge, care, and proper technique, you can easily […]
BERKELEY NUCLEONICS SETS INDUSTRY BENCHMARK WITH INTRODUCTION OF NEW MICROWAVE / RF FREQUENCY SOURCES Berkeley Nucleonics commercially releases a full line of high performance, robust, and extremely cost effective Microwave / RF signal generators. This […]
By Paul Roberts There are many potential sources of human and measurement errors in RF calibration. This paper examines five common error sources associated with connectors, cables, and accessories such as adapters, splitters and couplers: […]
By Hock Eng Lim This latest Metrology 101 articles shows us how to use new standards to calibrate the reference calibration output of a power meter. Read the Full Article (PDF)
The latest generation network analyzer from Rohde & Schwarz now also comes with four test ports and a second internal generator. Users who need to characterize multiport DUTs, mixers and amplifiers will benefit from the […]
